BufferedStreams doesn't work with ZipFile.jl

[xiaodaigh]

Expected Behavior

Expected it to work with ZipFile.jl which is using an io stream

Current Behavior

Errors

Possible Solution / Implementation

Implement the seekend method

Steps to Reproduce (for bugs)

using ZipFile, CSV, DataFrames, BufferedStreams

a = DataFrame(a = 1:3)
CSV.write("c:/data/a.csv", a)

# zip the file; Windows users who do not have zip available on the PATH can manual zip the CSV
;zip c:/data/a.zip c:/data/a.csv

io = BufferedInputStream(open("c:/data/a.zip", "r"))
z = ZipFile.Reader(io)

df = CSV.read(z.files[1])
close(io)

I get this errro

ERROR: MethodError: no method matching seekend(::BufferedInputStream{IOStream})
Closest candidates are:
  seekend(::Base.SecretBuffer) at secretbuffer.jl:150
  seekend(::Base.Filesystem.File) at filesystem.jl:227

Context
